DSP integrated coaxial line array

Extremely compact & powerful 3-way, self-powered (2800 W Class-D with PFC), DSP integrated coaxial line array element. Dual high power 8″ neodymium transducers and a unique 8″ dual diaphragm coaxial planar wave driver.


The CLS-28 is a high-output extremely compact and extremely powerful 3-way, self-powered, DSP integrated, symmetrical coaxial line source element designed for medium sized touring & fixed installations.

It uses two low distortion 8” (2.5” DUO copper voice coil) custom speakers for the low frequencies with exclusive Malt Cross cooling technology, FEA optimized neodymium magnet circuit, aluminium demodulating ring and waterproof cone.

For the mid/high frequencies it uses an ultra light 8” dual diaphragm coaxial planar wave driver. The unique voice coil technology employs a light weight copper clad aluminium wire, wound inside and out of the Kapton former to improve heat dissipation, dramatically increasing the acoustic output and reliability of the driver while minimizes the power compression.

The larger annular midrange diaphragm covers the frequency range between 550Hz and 6.3KHz with a smooth, linear response. The ultra light annular diaphragm for the high frequencies offers exceptional transient response with very high efficiency from  6.3KHz to 22Khz. With two subsystems in one each driver covers a smaller frequency range for increased power handling, high dynamic and extremely low distortion and delivers excellent phase coherence & perfect time alignment without problems of multi-source interference. Thanks to the mid range’s extended low bandwith (550Hz) the CLS-28 is able to deliver an unmatched 100º horizontal constant directivity coverage pattern.

The 2800W 2 channel Class-D amplifier with PFC (Power Factor Correction) offers exceptional efficiency with maximum system performance whilst significantly lowering power consumption. With Thermal, short-circuit and overload protections the system module delivers superior sonic performance. Coupled together with our new generation, 64 bit/96KHz processor the system electronics are yet further guaranteed not only the utmost protection but the best sonic performance.

Designed in-house by Lynx Pro Audio engineers our DSP offers the most recent advances in digital processing such as FIR filters delivering a linear phase & frequency response. The latest 32 bit/96KHZ AD/DA converters make the system one of the most advanced & innovative line arrays on the market resulting in pristine sound quality.

A 2.8” IPS user interface is located on the enclosure’s back panel and has multifunction joystick control enabling the user to control, select and/or adjust parameters such as cabinet presets, gain, delay and input EQ (see user manual). Two Ethernet ports enable the system to be controlled with the OCS platform for easier alignment, monitoring and processing of the array and together with the new Rainbow 3D prediction software delivers a complete system design tool.

The enclosure is made from premium grade birch plywood and finished with a polyurea coating for longer durability & weather protection. It also has a number of dedicated accessories available and the 3 point rigging system which includes 2 front automatically rising plates and 1 centre/rear point enables 16 CLS-28 cabinets to be flown in a single array. The system can also be rigged and angled in retracted position enabling a  much easier set-up without the need to lift each cabinet individually.

More features

Hardware for CLS-28

The CLS-28 cabinet is constructed from 11-ply premium birch plywood (15mm thickness) and finished with polyurea coating

Internal design

The internal structure of the CLS-28 is heavily braced for greater longevity and all parts are assembled on metal inserts with metric screws. The amplification modules & DSP are housed in a separate chamber to the drivers avoiding excessive heat & vibration, thus delivering greater efficiency and reliability.

Rear panel

The powder coated steel rear panel contains all connections and houses the CLS-28 amplification modules and DSP, is easily accessible and housed separately from the drivers for increased reliability and efficiency


The CLS-28 has two heavy duty, powder coated front grille with a special acoustic rear fabric to protect the transducers against dust and dirt.


The CLS-28 has four ergonomic handles with firm internal grip to facilitate transport, positioning and loading of the cabinets.  Two handles are placed at the rear of the cabinet and two L-shaped are located on the sides.


The 3 point rigging system with 2 front retractile levers and 1 centre/rear point enables up to 16 CLS-28 cabinets to be flown in a single array, with optional splay angles, from between 0º to 10º with 1º step increments to create the desired curve.

The system can also be rigged and angled in retracted position enabling a much easier set-up without the need to lift each cabinet individually.


The CLS-28 is easy to transport thanks to its dedicated flight case where it can be stowed in rest position. With craddle option: no need to lock pins.
